Carnivores also rely on plants because the herbivores are their source of food, and the plants feed the herbivores.
Explanation:
Soil moisture is a key variable in controlling the exchange of water and heat energy between the land surface and the atmosphere through evaporation and plant transpiration.
The green house effect is a natural process that warms the Earth surface.

Answer:
The repeating subunits of DNA are ribonucleotides whereas in RNA they are deoxyribonucleotides.
Explanation:
Ribonucleotides are repeating subunit of RNA while the deoxy-ribonucleotides are repeating subunits of DNA. That why RNA full form represent the ribonucleic acid and DNA represent deoxyribonucleic acid.
Actually the word "deoxy" means one oxygen is removed or less in DNA. The DNA lacks the one oxygen atom of hydroxyl group at carbon number two of ribose sugar. While RNA have the hydroxyl group at carbon number two of hydrogen atom.
The removal of one hydrogen atom in DNA make it more stable than RNA because DNA is made specifically to store genetic information and needed to be strong. The oxygen atom in RNA makes it vulnerable for attack by other biological molecules.
In plants the endosperm is the structure that forms from a triploid nucleus and nourishes the seed when a plant undergoes double fertilization.
